Pulling into a gas station is pretty mundane. You need gas, so you fill up. But do you ever stop to think about how much gas is in your engine? If you still have an owner’s manual, it tells you the number. But if you lost it,

How big is the gas tank on a 2005 Honda Civic?

One of the best-selling sedans on the market, the 2005 Honda Civic has a gas tank that holds 13.2 gallons. If you buy the compact natural gas trim level, you’ll get a gas tank with 7.2 gallons.

Unlike other vehicles that have different configurations and, thus, different tank sizes, the 2005

Civic has one tank size only (not counting the CNG version), so you’re not going to see any variance.

How to check your 2005 Honda Civic gas tank size

If you want to know how many gallons of gas your tank holds, there are ways to do it yourself.

Measure the gas tank

If you want to measure the tank yourself, you will need a calculator and some measuring tape. To figure out how much gasoline the tank holds, multiply the width, length, and height of the tank and divide the result by 231 (that’s the number of cubic inches in a gallon).

Check your owner’s manual

If you do know where your owner’s manual is, just open it and search for “fuel tank capacity” in the index. You should find the answer there!

Drive till empty, then fill it up

If you are feeling particularly daring, drive your car until the fuel gauge reads “E.” Then, when you stop for gas, fill the tank up as much as you can. This won’t give you an exact measurement, but the meter on the fuel pump will show you a pretty close approximation to your tank’s full capacity. Just make sure you don’t drive so far on an empty tank that the car runs out of fuel.

How to save on fuel costs in a Honda Civic

With the 1.8-liter engine in the Honda Civic, you can expect to get around 40 mpg combined, which is quite good.

The CNG trim level will give you around 28 mpg combined—so a little less. But keep in mind the gas tank is also smaller, so these numbers make sense.

With that in mind, you still might want to conserve money when you fill up. Here are some tips:

Maintain your vehicle regularly. Small issues can become big issues, which can lower your fuel economy. By keeping your car running smoothly, you’ll maximize your fuel efficiency.

Drive smart. Don’t speed up and slow down quickly. Keep it steady behind the wheel to get better fuel economy.

Don’t let it idle. If you turn on your car in the morning and let it warm up in the driveway, you’re wasting precious fuel. Leave the driveway right away—especially when it’s chilly—and warm up the car on your drive.
